Installing Equipment 

This section provides information on how to install rack-mount equipment in the enclosure. The 

instructions provided with the equipment provide more detailed information. 

Identifying one U-space on the vertical mounting flange 

When installing equipment, locate the top and bottom of a U-space on the mounting flanges. Every third 

hole on the mounting flanges of a NetShelter enclosure is numbered to indicate the middle of a U-space. 

A U-space consists of one of these numbered holes and one hole directly above and below it, as shown. 

Installing cage nuts 

APC offers a cage nut hardware kit (AR8100) for use with square holes. 

Warning: Install cage nuts horizontally, with the ears engaging the sides of the square 

hole. Do NOT install cage nuts vertically with the ears engaging the top and bottom of 

the square hole. 

1. Insert the cage nut into the square hole by hooking one ear of the cage nut assembly through the 

far side of the hole. 

Note: Install the cage nuts on the interior of the vertical mounting flange. 

2. Place the cage nut tool (not provided) on the other 

side of the cage nut and pull to snap it into position. 

Removing cage nuts

Equipment Planning Guidelines 

18 

Please note the following guidelines for proper installation and operation of hardware in a NetShelter CX 

Enclosure. 

Avoid clustering hot-running equipment 

such as servers, dense redundant arrays of 

independent disks (RAID), and large 

voice-over-internet-protocol (VOIP) 

switches in one part of the enclosure. 

Distribute the thermal load evenly up and 

down the enclosure such that each fan 

module supports an equal amount of the 

thermal load. 

Each fan module has a triangular metal 

section protruding slightly into the 

enclosure. This does not create an issue for 

installation of most equipment, but to 

allow for ample cabling space to the rear 

of the enclosure, deep servers should be 

installed in the enclosure space above and 

below these triangular metal protrusions.

Cable Management 

The NetShelter CX enclosure has a cable access opening at the rear the enclosure. Six vertical 0U 

accessory channels are factory installed in the AR4018, AR4018I, AR4024, AR4024I and four in 

AR4038 and AR4038I enclosures. Also provided in the front of AR4038 and AR4038I enclosures are 

vertical cable management clips in place of an accessory channel. APC offers a variety of other cable 

management accessories. 

Rear cable access port 

The cable port is large enough to accommodate several hundred ethernet cables and has a removable top 

cover. The design is such that pre-terminated data distribution panels can be installed effortlessly, with 

no need for de-termination and re-termination. 

To install or remove the rear cable access port see 

“Installing the rear cable port” on page 11. 

Vertical 0U accessory channels 

The vertical 0U accessory channels provide toolless mounting capabilities for APC Rack Power 

Distribution Units, APC cable containment brackets, and tie-off locations for cables. The standard 

position for the accessory channels is two located in the front of the enclosure and four in the rear of the 

enclosure. 

Removing vertical 0U accessory channels. 

Vertical 0U accessory channels can be 

removed completely from the enclosure. 

Loosen the fasteners that attach the vertical 

0U accessory to the enclosure.
